Abstract: An interconnection assembly for electrically connecting the contacts of an integrated circuit device with the contacts of said circuit board. The interconnection assembly having a base removably and adjustably attached to the circuit board and further having a preselected configuration for accepting the integrated circuit device therein such that the contacts thereon are aligned with the contacts on the circuit board. A bladder-like member having fluid therein is interposed between the integrated circuit and a closure element for forcing the bladder-like member into contact with the integrated circuit device thereby causing the contacts thereon to make electrical connections with the contacts on the circuit board.

Abstract: A ball grid array socket with rows of electrical contacts that extend through holes in a plate. The arrangement of the holes and the electrical contacts provides an entry hole. The contacts are arranged with ends that are cupped to mate with the side and top of the ball contacts of the ball grid array package. The contact surface of the ball grid array package is vertically inserted without any interfering structure. The plate is spring loaded is such a way that the plate is driven parallel to the plane of the ball contacts in a manner that reduces the entry hole opening. This reduced entry opening is arranged and constructed such that with a ball contact insert therein electrical conductivity is provided between the ball contact and the electrical contact, and further where the cupped ends of the electrical contact retain the ball within the hole. The edges of the hole and the top of the cupped electrical contact are chamfered to mate with the curved sides of the ball contact.

Abstract: An integrated circuit carrier system having a carrier frame made up of a plurality of juxtaposed sides and an interior configuration sized to matingly engage an integrated circuit package. The integrated circuit package fits within the frame and is held in position therein by a plurality of locking clips which slidably engage a plurality of top and bottom channels diagonally disposed at each of the corners of the frame. Each locking clip is made up of a substantially C-shaped structure having an uppermost leg and a lowermost leg. The uppermost leg ends in a substantially perpendicularly disposed locking tab and the lowermost leg has a variety of locking arrangements, one of which permits the locking clip to be locked in two locking positions. In one locking position the integrated circuit package is held securely in place while in the other locking position the integrated circuit package may be inserted or removed from the carrier.

Abstract: An aligning socket for an IC that provides an aligning bar that aligns and secures IC leads to the corresponding socket contacts (6), and where the bar has extensions or ears (42) that extend toward the row of IC leads (38). The ears have chamfered edges that, as the bar is forced toward the IC leads, guide the IC leads to mate with the socket contacts. For more fragile gull-winged leads, a rail 18 is provided to support the under side of the leads and the alignment bar ears are designed to fit over the ends of the rail. When the bar and socket contacts are forced toward the IC leads, the bar ears overlap the ends of the rail and force any mis-aligned IC leads to move such that alignment of the leads and the socket contacts is achieved.

Abstract: An IC test/burn-in socket with spring cantilever beam contacts and a lid 4 that provides for self-aligning of the IC lead and the socket contacts 6. The lid is actuated from above, and the lid has three positions--one for an unloaded socket, one for holding the contacts apart for insertion of an IC, and the other for releasing the contacts such the the spring force of the cantilever beam contacts make electrical contact with the IC leads. The cantilever contacts are arranged in interdigitated rows. The flat cantilever contacts allow the contacts to spread a substantial distance to achieve the desired contact force and will thus accommodate a wider range of IC lead thicknesses and, so, be more forgiving than earlier designs. There is a lid with troughs to guide the contacts and a through hole whereby an IC is inserted. The troughs and through hole provide improved registration of IC lead to socket contacts.

Abstract: A system for protecting a gull-wing IC providing a carrier (5) that mates to a programming socket (21) and to a development socket (40). The IC need not be removed from carrier throughout the handling, test/burn-in, programming, and final assembly on the PC board. Moreover, the footprint of the output electrical contacts on the development socket match the footprint of the IC leads, so that the etched PC board pads will accept the IC leads or the development socket output contacts, wherein the assembler may mount the IC using the carrier and the SMT socket or not.

Abstract: A bus bar assembly including an elongated insulative base member and a plurality of modular insulative unit pieces attached to the base member and having contact receiving openings, conductive bus bars in an enclosed region defined by the base member and unit pieces, contact pins of the bus bar extending upward into insulative tubular members extending downward from and centered within the openings, insulative fins supporting the bus bars above a bottom wall of the base member, an insulative divider wall between adjacent bus bars extending upward from the bottom wall, mounting holes in the upper and lower walls, and an insulative shield between the region between mounting holes and the bus bars.

Abstract: A socket for an electronic component having conductors for making electrical connection, the socket comprising a base member, a plurality of resilient contacts that are mounted on the base member at contact support portions and have free contact ends for engaging the conductors of the component, the contacts also having inwardly-directed first cam surfaces, and a component support that is slidably mounted with respect to the base member and contacts along an axis and has outwardly directed second cam surfaces that act to displace the contacts transversely to the axis as the component support is moved along the axis.

Abstract: A low insertion force electrical connector having a plurality of bent contacts with free ends that are movable by cam means in two stages in a cavity for receiving mating contacts on an electrical component.

Abstract: An electrical connector with an elongated heat-conducting, electrically-insulating member contacting electrical contacts on both sides of it, so that all contacts are maintained at the same temperature, to avoid voltage and/or current discrepancies of thermal sensing conductors through contacts owing to temperature differences.
